Electronic cigarette
An electronic cigarette includes a shell and a mouthpiece. The external wall of the shell has an air inlet. An atomizer and a liquid-supply are in contact with each other. The air inlet, atomizer, an aerosol passage, and a mouthpiece are sequentially interconnected.
1. An electronic cigarette, comprising:
a housing having an inlet and an outlet;
a liquid storage body in the housing holding a liquid;
an air flow path through the housing; and
an atomizer in the housing between the inlet and the outlet including:
a porous body in contact with the liquid storage body; and
a heating wire in the atomizer surrounded by the porous body.
2. The electronic cigarette of claim 1 with the liquid storage body including fiber material.
3. The electronic cigarette of claim 1 wherein the housing comprises a cylindrical tube having a central axis and the heating wire extending in a direction substantially perpendicular to the central axis.
4. The electronic cigarette of claim 1 further including a battery, a sensor and an electronic circuit board within the housing, with the circuit board electrically connected to the battery, the sensor and the heating wire.
5. The electronic cigarette of claim 4 further including a vapor-liquid separator separating the sensor from atomizer and the liquid storage body.
6. The electronic cigarette of claim 5 with the vapor-liquid separator comprising a check valve covering a through hole.
7. The electronic cigarette of claim 5 with the vapor-liquid separator comprising plastic or rubber.
8. The electronic cigarette of claim 1 with air flow channel connecting the inlet to the outlet, and with part of the air flow channel alongside of the liquid storage body.
9. The electronic cigarette of claim 1 with the heating wire comprising a wire coil.
10. The electronic cigarette of claim 1 further including an atomization cavity within the atomizer.
11. The electronic cigarette of claim 1 with the outlet within a mouthpiece that is screwed onto the housing.
12. The electronic cigarette of claim 1 with part of the air flow channel alongside the liquid storage body source.
13. The electronic cigarette of claim 1 wherein the porous body comprises a porous bulge section which projects into the liquid storage body.
14. An electronic cigarette, comprising:
a housing having an inlet and an outlet;
a liquid storage body in the housing holding a liquid;
an air flow path through the housing; and
a porous cylindrical atomizer in the housing between the inlet and the outlet, with the porous cylindrical atomizer in contact with the liquid storage body; and
a heating wire coil within and surrounded by the porous cylindrical atomizer.
15. An electronic cigarette comprising;
a housing having an inlet and an outlet;
an electronic circuit board and an atomizer having a heating element, within the housing;
a battery electrically connected to the electronic circuit board;
a stream passage within the housing leading from the inlet to the atomizer;
a liquid storage body including fiber material in a cylindrical section of the housing, with the liquid storage body in physical contact with the atomizer; and
an aerosol passage from the atomizer to the outlet.
16. The electronic cigarette of claim 15 further including a sensor in the stream passage, with the sensor electrically linked to the electronic circuit board.
17. The electronic cigarette of claim 15 with the heating element comprising a wire coil in a cavity in the atomizer.
